What changes were proposed in this PR?

Upgrade JTS from 1.19.0 to 1.20.0.

Most of the changes are made to the tests due to different computation results obtained from 1.20.0. The following functions are affected from the observations of broken tests:

• ST_MaximumIncribedCircle
• ST_VoronoiPolygons
• ST_TriangulatePolygon
• ST_Buffer
• ST_ConcaveHull

ST_MaximumIncribedCircle has significant changes, while other functions only introduce slight coordinate value changes.

Passing tests.
